Hello friend...Thank you for the opportunity to help you with your question :-)
If you add EXCESS Ca(NO3)2 to the solution the Ca+2 ions will combine with the SO4-2 ions and form a solid. Filter the solution to remove the sulfates. Once that is done, take the clear solution and add AgNO3. The Ag+ ions should combine with the acetate ions to form silver acetate solid. Filter as before. For this question you need to have a solubility table. you can find it here online..many webites provide it or you can also access it from your chemistry course book.
Here is the complete answer! Please let me know if you need any clarification. Please best with a 5*. Thank you and Godbless!!!
sorry i dint even realize i was answering the wrong question...Here is what I would do. Add Barium chloride.If a ppt forms carbonate is present.Add silver nitrate. If a ppt forms acetate is present.PPts are Barium carbonate and silver acetate.Carbonate can be confirmed by adding HCL, Solution will release CO2. Acidified solution when warmed should give an acetic acid smell if acetate is present..
you would ask me why, based on the solubility table, you would use barium?
this is why, ferrous carbonate is insoluble so ferrous nitrate should ppt it.I used Barium chloride as another substance to do the same..i hope it is now clear.
